module / function needed for profile tagging

I need some sort of 'extended profile tags' module, either a new setup, or mod on the existing one...

Need to have...

Profile Tags in join / edit profile (be added to profile builder blocks)

These must then show in a block on Profile page, as well as in a block on Browse or Search members page.

They must act as tags do, so if you click on one, it will show all profiles using that tag.

Visually, either same system as current 'tags' where the most used becomes bigger, or in 'rank order' where the most used is pushed to first... kinda like a tag chart!

doesnt need to be searchable as would be in its own block on browse / members search page to act as a filter.

Anyone interested? or can anyone think of anything already in existence that could be adapted?

I have a mod in development called "Interests" which mimics the "Interests" feature of www.badoo.com . This should cover most of your requirements.

 that could be useful...

How far into development are you with it?

Would it allow to create custom interests or are they pre-defined? 

The mod will be released sometime in December. It will allow both predefined and custom interests.

just checking out badoo at the mo as not used it before. 

One thing that would be really handy with the 'interest tags' is for them to work as filters with some sort of interest cloud on the members / search page. 

So when a user clicks on one 'interest tag' it searches all users with same tag. Is this in the design?
